Consistent Quality Liquid Silicone Rubber For Regular Mass Molding Tasks
Product Overview

HN-620 A/B belongs to condensation-cured two-component liquid silicone rubber, consisting of base compound A and curing agent B. The standard weight mixing ratio of A to B is 100:2. After thorough uniform stirring, the mixture does not require heating or extra equipment; it can undergo complete cross-linking curing naturally under normal room temperature conditions.

Applications

HN-620 A/B is industrial-grade liquid silicone rubber engineered specifically for construction mold production. It excels at casting and replicating molds for large natural stone, gypsum articles, cement components, cultural stone, artificial stone, Roman columns, stone carvings and a wide range of architectural & decorative ornaments. Beyond construction use, it is also ideal for fabricating split molds for resin crafts, gypsum artworks, handmade soap, tire casting molds and other handicraft products.
